    Sounds like you were using the wrong or a corrupt file.

    Welcome to Android Central! Did the bootloop start before or after installing the update? Did you root the phone, and have you been modifying it with various ROMs?

    The boot loop started after an OTA update, the phone didn't turn off during update because of low battery or so, after the update. The boot loop issue started

    It is not rooted and the phone has never been modified since purchase. I was trying the update through an SD card to fix the boot loop issue

    I have tried installing the stock room through sd card and an update file but same "wrong footer, signature verification issue". Is there a way I can get a legit update file if the one I'm using is wrong or a signed stock rom?

    How old is the phone -- is it still under warranty? Since this was an official system update from Infinix, they should be responsible for any problems it causes. Try contacting their support: https://www.infinixmobility.com/care/support

    It was bought early last year, I don't think it's still under warranty. Is there another way I can fix it?

    And sincerely the warranty process in my country is not something I've seen work before. I will prefer fixing it myself.

    Ok, it's still worth contacting their support to see if they can help with reflashing the stock ROM in a bootlooped phone. Another good resource would be the forums at XDA-Developers.com.

    I downloaded some from some sites and forums talking about using miracle box Qualcomm flash software and some other software but all attempts failed and it seems the version of files I have isn't signed, an infinix forum said I should back up the rom of an existing phone of exactly same model or update file and use but can't find one

    Hi, best place is to ask on XDA forum , im not sure you'll get much help here as its not as popular as Samsung, Google, LG etc

    You might have to flash through adb commands.
